Bilateral C6-7 interfacet joint dislocation.
Antroposition of C6 over C7 secondary to the dislocation.
Widened space between the spinous process of C6 and C7 due to ligament rupture.
Case Discussion
A bilateral facet dislocation is an unstable flexion distraction type of dislocation of the cervical spine, often a result of buckling force. Occasionally, the bilateral facet dislocation has been named a 'doubly-locked' vertebral injury, giving the impression of stability. However, due to complete ligamentous disruption, this is, in fact, an unstable injury.
